Hi,
I am using G4 to simulate the photonuclear reaction 197Au(γ,n)196Au. I constructed a thin gold layer where I shoot gammas in order to induce the reaction and produce 196Au. The number of atoms produced helps me calculate the cross section of the reaction for a given photon energy. I am doing this because I want to compare this results with real measured cross section values, in order to see how accurate is the model used by G4. I read that the best physics list for this simulation is QGSP_BERT_HP, so this is the one I have used. The cross section distribution that I got with this method is fine but the peak energy should be 13.5MeV and G4 gives me the peak at 14.5MeV.
I am writing to ask first if QGSP_BERT_HP is the best physics list that I should use for this purpose. Second, I would like to know if it’s possible to find out the exact cross section values that G4 is using for this reaction. The physics model G4 is using in my applications should have any type of tabulated cross section values, which I am not sure where I could find it. Maybe in the source code or somewhere else.
Thank you.
